Yep - all hardware has now been removed - and there is nothing that is
in the system when DOP-Mii is selected. Still same black screen. I'm
half wondering if there isn't an error message that isn't displaying
on my TV - as if it's a DOS-Text type error, they don't seem to scale
quite right. I may take it to a CRT-based TV and see if there is a
message there. Otherwise, I'm out of ideas...blah.
